Description
Technical field
The present invention relates to a kind of calculator room equipment cooling system in parallel.
Background technology
The sixties in last century, along with the communication Development of SPC Switching Technology, building environment can not satisfy the service requirement of programme-controlled exchange, exchange room need a kind of under various environment all spendable heat-removal equipment, because the influence of intrinsic fixed pattern, the dealer has generally expected the air-conditioning technical that reached its maturity at that time, and the mentality of designing of air conditioner in machine room continues into the present, and also steps into market environment instantly in the late comer constantly improves.
Because air conditioner in machine room can satisfy the environmental requirement of programme-controlled exchange, last century, the seventies was until last century end, the swift and violent development of program controlled switch technology has given air conditioner in machine room a slice wide sky, there is a large amount of domestic and international producers to enter the industry during this time, design and produce the special air conditioning for device room of various brands and form, China last century the eighties progressively introduce program controlled switch technology, also be to begin progressively to touch special air conditioning for device room in that time, also occur the production that a collection of domestic manufacturer carries out air conditioner in machine room afterwards, this stage belongs to the prime time of air conditioner in machine room.
Enter 21st century, data and Network begin to enter into the market, compare programme-controlled exchange, explosive growth has appearred in the caloric value of the data and the network equipment, in this case, the mentality of designing of continuity stored-program control exchange heat extraction has progressively shown the tired attitude of technology, is difficult to the technology situation that follows up new, and the technical bottleneck that some can't be ignored occurs.
Concrete technical bottleneck is as follows: 1, huge energy consumption: according to incompletely statistics, all kinds of machine rooms of current stage, air-conditioning power consumption ratio is near about total half that consumes energy of machine room, and this part power consumption can't produce any direct economic benefit, only be in order to ensure the running environment of calculator room equipment, indirect produces economic benefit by calculator room equipment.
2, huge volume: at present, design the most exquisite air conditioner in machine room main frame, comprise that every square meter of safeguarding station takes up an area of the apparent cold that not enough 20KW only can be provided, and in the present machine room, Single Cabinet (floor space less than one square meter) can reach more than 20 kilowatt caloric value easily, that is to say, just need to be equipped with the air-conditioning (machine room takes up an area of about 1.5 square meters) of more than 20 kilowatt of refrigerating capacity separately at a rack (floor space less than one square meter).
3, Ang Gui maintenance cost: because the operation of big load throughout the year, air conditioner in machine room must satisfy the maintenance levels of high request in the high request design, the core technology of air conditioner in machine room belongs to the Refrigeration Technique of nonlinear multivariable simultaneously, quite high for the specification requirement of safeguarding and keep in repair, must pay the stable operation that expensive maintenance cost could satisfy air conditioner in machine room.
It should be noted that according to Moore's Law: open ended transistor size on the integrated circuit, just can double every 18 months approximately, performance also will promote one times! The lifting of performance certainly will bring the lifting of heat simultaneously, that is to say, under ever-increasing market environment and customer demand, such heat generation density record is refreshed continual.Estimate that simultaneously because development of science and technology, existing calculator room equipment low in calories (as switch) also can be substituted by data equipment sooner or later according to us, caloric value also can be progressively near the level of present IDC machine room.Existing machine room heat radiation level all can't bear the heavy load for air conditioner in machine room, and so if things go on like this, air conditioner in machine room will be difficult to reply!
Introduce the technical characterstic and the operation logic of machine room lower air-conditioning below in detail:
1) concentrate the air supply mode temperature control:
Air conditioner in machine room adopts is that the method for the whole room air of circulation is carried out indoor temperature control, mode of operation is: after air-conditioning reclaims room air and detects humiture by powerful blower fan collection, be transmitted back to indoor after the humiture that air-conditioning carries out indoor environment and needs the air that reclaims is handled; After high-power blower is delivered to treated suitable air in the calculator room equipment, absorb the heat that calculator room equipment sends, the intensification air is device for transferring inside under the effect of high-power blower again, gets back to air-conditioning by the machine room space at last, air-treatment is finished in the circulation that so goes round and begins again.In whole circulation, high-power blower is indispensable, can be described as the soul of air conditioner in machine room even.
The refrigerating system of air-conditioning and supply air system are two indispensable necessary component, show cold with a nominal refrigerating capacity 18KW() air conditioner in machine room be example, the compressor power consumption of its outfit is about about 5KW, is that the blower fan power consumption then is 2KW even higher.We know that the refrigerating capacity equipping rules of machine room is the cooling demand when satisfying maximum heating load at least, according to the control logic of all air-conditionings; after indoor temperature reaches set point; compressor will be shut down, but in order to keep indoor normal wind circulation, blower fan will run without interruption.Simultaneously, even this machine room does not exist any refrigeration plant or refrigerating capacity backup, the compressor of this air-conditioning also can be in the state of intermittent duty always.According to incompletely statistics, one without any the intact common machine room of refrigerating capacity backup insulation measure, and the annual duty ratio of compressor will be about 50%, and indoor fan will run without interruption, and 10,000 hours be example with this 18KW operation of air conditioner:
Compressor power consumption: 5KW*10000 hour * 50%=25000 degree
Blower fan power consumption: 2KW*10000 hour * 100%=20000 degree
Following situation occurs and will further reduce the compressor duty ratio:
A), machine room insulation measure imperfection, the air-conditioning cold flow configuration is higher; B), there are backup air-conditioning or backup refrigerating capacity; C), the machine room dilatation increases refrigeration plant; D), adopt various air conditioner energy saving measures.
2), adopt refrigeration modes to carry out transfer of heat: our common special air conditioning for device room all adopts various types of refrigeration modes to finish the inside and outside exchange heat of machine room, when outdoor temperature is higher than indoor temperature, it will be a kind of indispensable mode that ensures computer room temperature undoubtedly, but the long-term mean temperature in most land areas all requires temperature (25 ℃) far below machine room in the whole world, change kind of a thinking and analyze, that is to say that the ambient temperature of global most land areas most time is lower than the temperature that machine room requires.Under the lower situation of outdoor temperature, if the cost of the mode that still adopts refrigeration by consumes power with the transfer of heat in the machine room outside machine room, to use natural cooling source to reduce computer room temperature be a kind of huge waste really and can not switch to easily.
3), big air quantity, big blast, little enthalpy difference: in order to satisfy the machine room complex inner structure, the air-supply air quantity and the wind increases of air-conditioning must be arrived enough each calculator room equipment air inlets of arrival, could satisfy the cooling requirement of calculator room equipment.And little enthalpy difference influences the security of operation of calculator room equipment mainly in order to guarantee that the cold wind that air-conditioning blows out is unlikely to produce the dewfall phenomenon on calculator room equipment.
4), energy consumption height, stability are higher than economic benefit: because the running environment of calculator room equipment is had relatively high expectations, in case occur to produce various operation troubless immediately under the situation that running environment exceeds standard, so the air conditioner in machine room design must guarantee continual high stability, could satisfy the continual requirement of calculator room equipment.Even if new new technology has more efficiently been arranged on the market, also very prudent application advances.Therefore, on Air-conditioner design, many economic factors such as efficient are had to take the second best often.
5), intelligent humidity control: calculator room equipment is made up of various circuit boards basically, operation has higher requirement to humidity, humidity is crossed and low is occurred static easily, too highly will cause various faults such as circuit board short circuit, add dehumidification system so the air conditioner in machine room majority all disposes, just often the humidity configuration is not rigorous in the air conditioner in machine room configuration.The configuration of humidification amount, dehumidifying effect is not common thing as calculated, will consume too many lost work during humidity control simultaneously.When particularly dehumidifying work, refrigerating system and electric heating system will be opened simultaneously, and the refrigeration instruction and the work order that adds, dehumidifies also often clash.
6), carry out the increase-volume expansion by the method that increases equipment:
The machine room design is to carry out the air-conditioning configuration for the requirement of machine room internal environment under the present case at first, air-conditioning equipment has also occupied the supply air duct of machine room the best simultaneously, when if situations such as later stage generation machine room increase-volume need increase refrigerating capacity, can only carry out increase-volume with the method that increases air-conditioning equipment, refrigerating capacity has also increased corresponding breeze fan power consumption when increasing, the breeze fan power consumption majority for original machine room air-supply level that increases belongs to idle work, but in order to satisfy big air quantity, the requirement of high blast and little enthalpy difference, can't reduce this part energy consumption again, with the useless energy consumption that increases greatly in the machine room.
The whole branch of programme-controlled exchange circuit board before is independently little thermal source, device interior does not have forced convection device to carry out hot transmission work simultaneously, need to use the high blast of big air quantity of air conditioner in machine room to carry out forced-convection heat transfer, but after entering the new century in the last few years, data, network, transmission and wireless telecommunications system fast development, occupation rate rises year by year, and the heating characteristics of these equipment have had very big difference:
1, circuit board is whole when being divided into independent little thermal source, and segment chip on the circuit board (as CPU) and parts (as power supply) become high thermal source, and high thermal source part is absolute has dominated calculator room equipment and even machine room gross calorific power.
2, main heating position has adopted independent radiator (most high hot CPU have adopted heat pipe-type independence radiator), and the calculator room equipment main frame has increased the forced convertion fan, helps the heat extraction of device interior toward equipment outer (in the machine room) in this way.
3, the humidity demand with identical before still be 40%rh-60%rh.
4, the whole heat of machine room is increased sharply, and programme-controlled exchange machine room before is the highest to be configured to every square meter machine room configuration refrigerating capacity 300W-350W, and present these data of IDC machine room significantly improve, and often a rack (0.8 square meter) caloric value can arrive more than the 20KW.
In sum, because the communications industry constantly develops, the calculator room equipment caloric value constantly increases, and causes original machine room heat dissipation technology various insoluble problems to occur, as the inner bottleneck such as uneven in temperature of huge, the machine room of consuming energy.Calculator room equipment is still constantly increasing operational capability and caloric value in addition, and if things go on like this air conditioner in machine room can't satisfy the demand of machine room heat radiation at last.
Illustrate: traditional machine room heat-removal equipment (air-conditioning, new wind, heat pipe, ethylene glycol etc.) all has characteristics, be exactly earlier the machine room space to be cooled off, be the calculator room equipment cooling by the suitable air themperature of machine room then, we are referred to as district cooling with it this indirect mode.
